How many polygons did you know? Can you name them?
In Geometry, polygons are closed figures with at least three sides. When I was in school back in the days (Elementary and High School), I thought polygons are up to 12 sides because I saw it on the poster posted in our math center. Later on, I learned that it has infinite number of sides and as the number of sides increases it getting closer to become a circle. Actually, it looks like a circle.

I made this images if the regular polygons using a software called Inkscape. It is free to download. I just have to enter the number of sides and I can easily draw any polygon based on the desired number of sides.
